SYNOPSIS
	int sscanf(string str, string fmt, mixed var1, mixed var2, ...)

DESCRIPTION

	Parse a string str using the format fmt. fmt can contain
	strings seperated by %d and %s. Every %d and %s corresponds to
	one of var1, var2, ... .
	
	%d stands for a number and %s for a string.
	
	The number of matched arguments will be returned.
	
	The function sscanf is special, in that arguments are passed
	by reference.

		   "throw %s to %s", what, who) != 2)
	   write("Usage: throw <what> to <who>\n");
